3.1. Internet Settings
3.1.1 WAN
The WAN (Wide Area Network) section is where you configure your Internet connection type.
Besides supporting 3G dialup connection type to access Internet, there are three WAN connection
modes to choose from: Static (Fixed IP), DHCP(Auto Config) and PPPoE(ADSL). If you are unsure
of your connection method, please contact your Internet Service Provider before configuring the
required parameters. Note: If using the PPPoE option, you will need to ensure that any PPPoE
client software on your computers is removed or disabled.
Through the Wan Weight function on this WAN setting webpage, you can set up the transmission
ratio among the Ethernet WAN and each 3Gs (WAN1: WAN2: WAN3: WAN4: WAN5) for the router’s
load balance. Default is 1:1:1:1:1.
Note: If the external dongle is not connected, the wan weight for it must be either 0 or empty.
To integrate the bandwidth of all WANs mentioned above for uploading packets, you can enable the
Upload Bandwidth Integration function which is much helpful to speed up the transmission of the
upload on this WAN webpage. Please also note that all WANs’ interfaces need the public IP address
in case of TCP packets.

3.1.1.1 Static(Fixed IP) WAN Mode
Used when your ISP provides you a set IP address that does not change. The IP information is
manually entered in your IP configuration settings. You must enter the IP address, Subnet Mask,
Default Gateway, Primary DNS Server, and Secondary DNS Server. Your ISP provides you with
all of this information.
3.1.1.2 DHCP(Auto Config) WAN Mode
A method of connection where the ISP assigns your IP address when your router requests one from
the ISP's server. Some ISP's require you to make some settings on your side before your router can
connect to the Internet.
Hostname: Some ISP's may check your computer's hostname. The hostname identifies your
system to the ISP's server. This way they know your computer is eligible to receive an IP
address. In other words, they know that you are paying for their service.

17
3.1.1.3 PPPoE (ADSL) WAN Mode
Select this option if your ISP requires you to use a PPPoE (Point to Point Protocol over Ethernet)
connection. DSL providers typically use this option. This method of connection requires you
to enter a User Name and Password (provided by your Internet Service Provider) to gain
access to the Internet.
Operation Mode: Typically, connections are not always on. The router allows you to set the
reconnection mode. The setting is:
Keep Alive: A connection to the Internet is always maintained. When this option is
selected, please enter a value in the field of Redial Period which is the time
interval the machine will be redialed before the PPPoE connection is disconnected.

3.1.1.4 3G Settings
This section is where you configure your dialup up connection type. There are 2 modem types to
choose from: Cellular 2G and 3G.
Up to four 2G/3G are allowed to be used at a time through one internal 2G/3G module and three
external USB ports for the connection of 3G dongles. With these multiple 2G/3G, they will balance
the load of WAN transmission for the router. Based on your USB1/USB2/USB3 hardware
configuration on G2wifi III_USB x 4, sequentially set up these cellular modems (See the figure
below).
2G/3G ISP Settings: Your 2G/3G service provider will provide you with the values to fill in for
the required fields of Access Point Name (APN Gateway),PPP User Name, PPP Password
and Dial Number.
Dial Number: The 2G/3G dial command. Default is *99#.
Authentication Mode: The mode for PPP authentication. Default is Auto.
Connection Type: There are four types of operation mode supported: 3G only, 3G+2G(3G
Preferred), 2G only, and 2G+3G(2G Preferred). Default is 3G + 2G (3G Preferred).

3.1.2 LAN
These are the settings of the LAN (Local Area Network) interface for the AP. The AP's local
network (LAN) settings are configured based on the IP Address and Subnet Mask assigned in this
section. The IP address is also used to access this web-based management interface. It is
recommended that you use the default settings if you do not have an existing network.
IP Address: The IP address of your router’s LAN port. Default: 10.10.10.254.
Subnet Mask: Subnet Mask of your LAN (default: 255.255.255.0). All devices on the network
must have the same subnet mask to communicate on the network.
DHCP Type: DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is
where you configure the built-in DHCP Server to assign IP addresses to the computers and
other devices on your local area network (LAN). When you select Server item from this
pull-down list to enable this function, the following parameters will be displayed. You must enter
the IP address, Subnet Mask, Primary DNS Server and/or Secondary DNS Server.

Start IP Address: Specify the DHCP Client IP address that will start.
End IP Address: Specify the DHCP Client IP address that will end.
Note: The number of the “End IP” must be greater than “Start IP”, and cannot be the same as the
router’s IP address.
DHCP Lease Time: Designate the amount of the time for the device to recycle and give out
the IP addresses to the devices in your network (default: 86400).
Statically Assigned: You can statically assign the client MAC and IP address. Up to three
IPs and MACs can be assigned.
